Abstract
Purpose
Organizing hematomas (hematic pseudocysts) of the orbit are usually the consequence of direct blunt trauma and are important in the differential diagnosis of orbital cystic lesion. Herein, we report a case of orbital organizing hematoma masquerading as a chalazion.
Case summary
A 12‐ year‐ old female visited our clinic complaining of left lower eyelid swelling. CT scan and MR imaging showed a mass detected in the inferomedial space of her left orbit, which did not invade the adjacent tissue. Excisional bi-opsy of the orbital mass was performed. Histological examination showed the accumulation of blood‐ breakdown products within a thick fibrous capsule without epithelial or endothelial lining. The mass was diagnosed as an organizing hematoma.

(A, B) External photographs show left lower eyelid swelling and partially protruded mass. At 1 month after surgery, the patient has no evidence of recurrence.
Figure 2.
Axial view of T1-weighted image (A) and co-ronal view of T2-weighted image (B) demonstrate 1.7 ×1.7 cm sized well-demarcated cystic mass in the inferior medial extraconal space of the left orbit. The mass shows high signal intensity in both T1 and T2-weighted images. There is maxillary sinusitis. (C) The mass shows poor enhancement.
